If one were to calculate T you would need to find the probability of 1 three, 2 threes, · · · , and 10 threes and add them all up. However, you can use the complement rule to calculate P(T ) Venn Diagrams; Probability Laws Notes Set Operations and Relations Venn Diagram Solution. 2.7 Venn Diagram Venn Diagrams; Probability Laws A Venn diagram is a diagram that shows all possible logical relations between a finite collection of sets. Set Operations and Relations Venn Diagram 2.8 Notes General Addition Rule Venn Diagrams; Probability Laws Notes The general addition rule is a way of finding the probability of a union of 2 events. It is P(A ∪ B ) = P(A) + P(B ) − P(A ∩ B ) Set Operations and Relations Venn Diagram 2.9 Inclusion–Exclusion Principle The inclusion–exclusion principle is a way to extend the general addition rule to...
